Element Emission

Off-Gassing or Element Emission refers to the Game Mechanics of one element reducing its mass to produce another element. In most cases this is a Gas therefore it's also often referred as Off-Gassing.

The Elements that exhibit this behavior will emit their respective Element if the surrounding Atmosphere is below 1.8kg in pressure. As a natural tile, they will check all 4 directions and only emit in the directions that are lower than 1.8kg pressure without favoring any direction, as long as that condition is fulfilled.

To bypass this 1.8kg pressure limit, because of the One element per cell rule, a debris can be submerged in a puddle of liquid of less than 1.8kg or natural tiles surrounded by puddles of liquids of less than 1.8kg, allowing elements to emit constantly, even if the pressure in the nearby cells are already way above 1.8kg. This can also happen unintentionally when, for example, a single tile of Carbon Dioxide from a Dupe breathing passes by.

Natural Tiles
Natural Tiles behavior is dependant on their own probability to emit their designated element every tick (0.2 seconds) Emission Rates in the table below are given in one direction, but these elements (with the exception of polluted water, which can only emit to the top) will calculate their emission in all 4 directions, effectively multiplying their emission by a factor of 4. Note that Polluted Mud would need to rest on an Airflow Tile to emit to the bottom, since it's subject to gravity. * While Polluted Dirt is a Element in the Vanilla Version of the game, it only ever appears as a Natural Tile in Spaced Out!. ** Both Polluted Mud and Dirt have their probability stated the game files as sublimateProbability: 0.05 However, the true/measured probability does not align with it.

Debris/Bottled
The rules for debris are rather difficult to test and find the proper equations for, and are very close approximations (to less than half a percent in deviation) to the true/measured behavior while not being too complicated to always follow $$factor_1 \cdot mass^{factor_2}$$ in g/s, with $$mass$$ is given in kg. * Not just for Slimelung with Slime, but any emitted elements, regardless of type and source, are always covered with germs proportional to the emitted amount to the remaining material.

Tips

 * Mined Oxylite debris emits the same amount of Oxygen as it would have as a natural tile.
 * Since Slime emission rate doesn't depend on its mass, loading it on Conveyor Rail, which separates it into 20kg chunks, lets it emit Polluted Oxygen much faster than leaving it in large debris chunks.
 * Bottled Polluted Waters emission rate is linearly dependent on its mass and will not give diminishing returns. Therefore it's easy to make it emits much faster, since bottles are not limited per cell.
 * Transporting Bleach Stone is an easy way to create a Chlorine atmosphere for disinfection.

Trivia

 * Polluted Mud and Corium only emits as a natural tile, not in debris form.
 * Bleach Stone and Slime only emit as debris, not in natural tile form.
 * Corium emitting Nuclear Waste plays the animation clean Air bubbles like Oxylite emitting Oxygen.
